NAME
     hme — Sun Microelectronics STP2002-STQ Ethernet interfaces device driver


SYNOPSIS
     To compile this driver into the kernel, place the following lines in your kernel configuration file:

           device miibus
           device hme

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

           if_hme_load="YES"


DEPRECATION NOTICE
     The hme driver is not present in FreeBSD 13.0 and later.  See
     https://github.com/freebsd/fcp/blob/master/fcp-0101.md for more information.


DESCRIPTION
     The hme driver supports Sun Microelectronics STP2002-STQ “Happy Meal Ethernet” Fast Ethernet interfaces.

     All controllers supported by the hme driver have TCP checksum offload capability for both receive and
     transmit, support for the reception and transmission of extended frames for vlan(4) and a 128-bit multicast
     hash filter.


HARDWARE
     The hme driver supports the on-board Ethernet interfaces of many Sun UltraSPARC workstation and server
     models.

     Cards supported by the hme driver include:

     •   Sun PCI SunSwift Adapter (“SUNW,hme”)
     •   Sun SBus SunSwift Adapter (“hme” and “SUNW,hme”)
     •   Sun PCI Sun100BaseT Adapter 2.0 (“SUNW,hme”)
     •   Sun SBus Sun100BaseT 2.0 (“SUNW,hme”)
     •   Sun PCI Quad FastEthernet Controller (“SUNW,qfe”)
     •   Sun SBus Quad FastEthernet Controller (“SUNW,qfe”)


NOTES
     On sparc64 the hme driver respects the local-mac-address? system configuration variable which can be set in
     the Open Firmware boot monitor using the setenv command or by eeprom(8).  If set to “false” (the default),
     the hme driver will use the system's default MAC address for all of its devices.  If set to “true”, the
     unique MAC address of each interface is used if present rather than the system's default MAC address.

     Supported interfaces having their own MAC address include on-board versions on boards equipped with more
     than one Ethernet interface and all add-on cards except the single-port SBus versions.

HISTORY
     The hme driver first appeared in NetBSD 1.5.  The first FreeBSD version to include it was FreeBSD 5.0.
